    Trouble shooting 1 Introduction to this chapter The Océ 3121/3122 has several ways to inform you about malfunction. The most important is the self-diagnosis system which generates an error code if there is something wrong with the basic machine. Besides that, the composite power supply of the machine can indicate malfunction in the power supply ar- ea, by a flashing LED on the composite power supply PBA.
